Several things make volumetric flasks the most accurate way to measure volumes of liquids. First, they are specially calibrated and tested so that the volume listed is exactly the correct volume, often to within 0.01 mL. Secondly their shape is specially designed for accurate measurement. They have a long narrow neck with a line to mark the correct volume. Because the neck is so skinny, the water level is much more sensitive to the amount of water than if the neck was much wider (like in an erlenmeyer).
Note that an erlenmeyer flask is about the worst thing I can think of to measure volumes! Much better than that is a graduated cylinder. A graduated cylinder, while somewhat less accurate than a volumetric flask does have the advantage of being able to measure different volumes, whereas a volumetric flask is designed to measure one and only one volume.
Erlenmeyer flasks and beakers are used for mixing, transporting, and combining chemicals, rather than for measuring. Experiments have shown though, that beakers are more accurate than flasks.

Which vessel is more appropriate for mixing by swirling a beaker or an erlenmeyer flask?
The Erlenmeyer flask's narrow neck allows more vigorous swirling without as much chance of spilling as with a beaker or other wide mouth vessel.
Is a beaker used to measure volume?
No, a beaker is a poor choice of instrument to measure volume. Instead try a graduated cylinder. Generally, the smaller the diameter of graduated cylinder, the more accurate it will be. A grad cylinder will have the increments written up along the side with carefully placed "hash marks" indicating the volume of substance/solution in the cylinder. A breaker may have a few markings indicating the volume of the contents up the side, but not enough make it an accurate measuring device for varying volumes of liquid.
What tools do scientists use to enhance their observational techniques?
Answerpencil and paper,Erlenmeyer flask, test tube, over flow can, test tube holders, test tube rack, Bunsen burner, tripod, safety goggles, safety gloves, safety apron, particle excel-orator, and much much more!
Round flask with long neck?
You could be referring to a florence flask or a volumetric flask.See the Related Questions links to the left for more information.
What is the use of graduate cylinder?
A graduated cylinder is a piece of laboratory glassware used to accurately measure out volumes of chemicals for use in reactions. They are generally more accurate and precise for this purpose than beakers or erlenmeyer flasks, although not as precise as a volumetric flask or volumetric pipet. They come in a variety of sizes for different volumes, typically 10 mL, 25 mL, 50 mL, or 100 mL and up to as large as 1 or 2 liters.
Which vessel is more appropriate for mixing by swirling a beaker or an erlenmeyer flask?
The Erlenmeyer flask's narrow neck allows more vigorous swirling without as much chance of spilling as with a beaker or other wide mouth vessel.
Can a beaker be used in a titration instead of an erlenmeyer flask?
Yes, a beaker can be used in a titration instead of an Erlenmeyer flask. However, beakers have a less precise shape compared to Erlenmeyer flasks, which can affect the accuracy of the titration results. It is recommended to use glassware with more precise measurements for titrations.
What is the difference between beaker and an Erlenmeyer flask?
A beaker is a cylindrical container with a flat bottom and spout for easy pouring, while an Erlenmeyer flask has a conical shape with a narrow neck. Erlenmeyer flasks are more suitable for containing substances that require mixing or swirling due to their shape, while beakers are better for holding and heating liquids.
What instrument which would be more accurate for measuring the volume of a liquid?
A graduated cylinder would be more accurate for measuring the volume of a liquid compared to a beaker. This is because graduated cylinders have more precise volume markings and allow for more accurate readings due to their narrow and uniform shape.
Whats the difference between an Erlenmeyer flask and a Florence flask?
An Erlenmeyer flask has a conical shape with a narrow neck, while a Florence flask has a round bottom with a longer neck. Erlenmeyer flasks are more suitable for mixing and swirling liquids, while Florence flasks are better for heating substances evenly.
What is the difference between a florence flask and an erlenmeyer flask?
A Florence flask has a round bottom and a long neck, often used for heating liquids evenly. An Erlenmeyer flask has a flat bottom and a conical shape, commonly used for mixing and storing liquids. Florentine flasks are better suited for distillation or reflux processes, while Erlenmeyer flasks are more versatile for general laboratory use.
What is Erlenmeyer flask and its uses?
An Erlenmeyer flask is a piece of laboratory glassware with a conical shape, a flat bottom, and a narrow neck. It is commonly used for mixing, heating, and storing liquids in the laboratory. The conical shape allows for more efficient mixing and swirling of liquids.
What is the best piece of lab equipment for holding 50 ml of boiling water?
A 50 mL beaker or Erlenmeyer flask would be suitable for holding 50 ml of boiling water in a laboratory setting. Both of these glassware items are typically heat-resistant and designed to withstand the high temperatures involved with boiling water. It's important to use caution and appropriate safety measures when handling hot liquids in the lab.
During titration why use a conical flask and not a beaker?
A conical flask allows for more efficient mixing of the reactants in the solution due to its narrow neck and shape. This results in more accurate and precise results during titration compared to a beaker, which has a wide opening that can lead to spillage and improper mixing. Additionally, a conical flask helps in preventing loss of volatile substances during the titration process.
What makes a type of glassware more or less accurate?
volumetric flask
How do you transfer any remaining solute into a volumetric flask?
To transfer any remaining solute into a volumetric flask, first dissolve the solute in a small amount of solvent in a beaker. Then, rinse the sides of the beaker with more solvent to ensure all the solute is transferred, and finally pour this solution into the volumetric flask and rinse the beaker multiple times to ensure quantitative transfer.
What is an Erlenmeyer flask used for in chemistry?
An Erlenmeyer flask is commonly used in chemistry for tasks such as mixing, storing, or heating liquids. Its conical shape allows for easy swirling of liquids without spilling, making it ideal for reactions where the contents need to be mixed or agitated. Additionally, its narrow neck minimizes evaporation of liquids, making it suitable for heating solutions.
